Jil is a fast JSON serializer and deserializer for .NET, built on Sigil to emit highly optimized code at runtime. It supports both static typed and dynamic (DLR-based) serialization and deserialization.
Use cases
- serialize c# objects to fast
- deserialize into typed .NET classes
- high performance parsing in asp.net
- serialize dynamic or expandoobject types to
- reduce serialization overhead in hot paths
When to choose
- you need maximum JSON throughput in .NET and can tolerate warm-up cost
- you want a lightweight serializer without heavy dependencies
- you need dynamic JSON handling with DLR support
When to avoid
- you need case-insensitive deserialization by default
- you want a batteries-included serializer with rich attribute-based customization
- you need actively developed features rather than maintenance
